摘要：1,249,291. Laminates. NATIONAL RESEARCH DEVELOPMENT CORP. 1 July, 1968[29 March, 1967], No. 14210/67. Heading B5N. [Also in Divisions Cl and D1-D2] A mat ofaligned fibres, suitable for impregnating with a matrix to give a composite material ismade by dispersing the fibres in a liquid, passing the dispersion through a nozzle so thatat least 85% of the fibres are aligned within 10 degrees of one direction, laying thedispersion of aligned fibres on a permeable surface moving relatively to the nozzle at avelocity at least that at which the fibre dispersion leaves the nozzle, and withdrawing theliquid through the permeable surface by suction rapidly enough for the alignment to bemaintained. The fibres may be of asbestos, carbon, silicon carbide or silicon nitride, andmay be \" whiskers \". The dried mat may be impregnated with a synthetic resin andlaminated, or cut into strips and wound on a former to produce an article, such as arocket motor. The synthetic resin may be a phenol-formaldehyde, epoxy, polyester or
silicone resin.
