alan_harper_-_Alan-harper-composites-ltdHello, first of all I would like to thank you for visiting our website.

We believe passionately in protecting the environment while providing you with the world’s most cost effective and efficient technology for composite moulding . Bringing you lower cost with world class reusable vacuum closed moulding system that removes permanently the need for costly and environmentally unsound use and disposal of one-time-use composite consumable waste.

There is a constant desire to reduce wastage, save money and operate cleaner composite production. Alan Harper Composites exists to achieve this. We offer affordable hardware and new proven technology which is outside the box of existing conventional consumable production thinking.

Alan Harper
CEO & Founder


Here you see for the first time why we are gaining so much attention from the composite moulding community. Between now and exhibiting from March 8th, at the biggest composites show in the world, JEC Paris, we will convince you, with client testimonials and global market users testifying why they have chosen our reusable vacuum membrane technology.
We say to everyone please do NOT buy anything from us or contact us if you do not want to save money, profit from better parts, lower scrap and cleaner less wasteful production. Thank you

O time da Fibrovent, atualmente na Green composites, nosso distribuidor no Chile foi um dos pioneiros em usar membranas de grande porte(16m2+) quando, a quatro anos atrás, implementou pela primeira vez o VPI™ nas sua linha de produção de equipamentos para a industria da mineração. A redução de custos chegou a um 40% comparado ao sistema de RTM Light utilizado anteriormente.
